To all 'wkomc't may concern i Be it known that I, JAMES R. ARMSTRONG, a resident of Pittsburgh, inthe county\of Allegheny and State of Pennsylvania, have invented certain new and'useful Improvements in Gas-Meters, of which the following .is a specification.

This invention relates to gas meters, and.. has particular reference to certain improve ments in the meter patentedy to me May 9,

ien, Ne. 991,927.

` One object is to provide avconstruction l whereby the parts may be assembled and adjusted before they are inclosed in the meter casing' A i rther purpose is tosim liy the construction, iparticularly with re erence to that portion o the ructure provided with the inlet and outlet. ports, in .the improved vadaptation the ports, the valves, and the valve actuating mechanism being carried by a head-like body which forms a closure for an open-top casing containing the measuring chambers. v

In the accompanying drawings, Figure 1 is a vertical longitudinal section` of the vimproved meter, taken on line 1-1' of Fig. 3, and Fi 2 is a'vertical cross ,section on line 2--2 o-Fig-. 3. Fig. 3 is a top plan with- Vplan at the top of the chamber-forming eas` i' inggand the other half 'is a sectional plan on line 4-4 of Fig. 2. Fig. 5 is a section of the'uppe-r portion of the meter taken on line 5-5 of Fig. 3.

The invention is here shown embodied in a meter of double form, there being two airsof 'measuring chambers with one chamr of each pair filling, while the other two cham Referring to the drawings, 2 designates:

4an open-top lcasing which is' divided into two chambers 3 and 4 by the central parti-- 'tion 5. The open-top of the casingis'v flanged at 2 and faced to receive the head-like body 6 which closes chambers Sand '4, body 6 and the upper cap-like casing 7 bein-gsecured to Ran-ges 2 bolts 8.

anism, includin the .supplemental measuring chambers 3 -and 4 located in the-main 9 open at one side and secured to the underside of body 6 by .a .flanged neck-like part chambers 3 and 4,'respectively. Each of the .I

10. They twocasings 9 are arranged back to back and separated suflciently to enter casing 2 at opposite sides of partition 5, so that when head 6' is 'in place a sup lemental measuring chamber is installed 'w1th ineach main measuring chamber, being sup-- therewith. v v v 4The open side of each chamber-forming ported entirely by head 6 and removable *1 casing 9 is closed by a liexible diaphragml 11 carrying the usual head-forming pan 12,

the diaphragm being secured to the casin and pan by wrapping 11 and 11, respectively. .Secured to each pan is a vertical spindle 13 which extends through guide 14 vdownwardly to a bearing 15, the guide and bearing being carried by arm 16 of irregular shape secured to flag rod 17, the latter having a bearing 18 on casing 9 and extending upwardly through head 6, as will presently be described. The diaphragm is prevelfi'ted from oscillating on arm 16 by the swlnging'guide l19 depending from the bearings 20 projecting from neck 10, the guide arms extending downwardly through loop 21 securedto pan 12.

- Head 6 is formed with two sets of ports, one set for each pair 'of measuring chambers. -Each set includes two inlet-ports 22 and 23 which establish communication be tween` the space inclosed by 'cap 7 and the measuring chambers, port 22 communicat-- ing with the main' measuring chamber 3 (or 4) and port 23` with the supplemental Chamber 3 (or 4').v Locatedbetween inlet ports 22 and'23 is the outlet port 24 which leads to the meter outlet 25, as shown in dotted lines in Fig. 3, also see Fig. 1. The three ports 22, 23 and 24 open through a valve seat 26 which is faced to receive slide valve 26. In Fig. 3 Only one of the two slide valves isshown; the other being removed to fully illustrate the valve seat and 'portsr 27 indicates the gas receiving chamber inclosed by cap 7 and to which gas is admitted through inlet connection 28.

i The mechanism for transmitting motion from flag rods 17 to the valves is the same as in my above mentioned patent and consists of arms 29 secured to the rods and crossing each other with their outer ends adjustably connected by links 30 withscrew stem 31 on the upper end of the double crank 32, the latter mounted in step bearing 33 carried by head 6. Extending from cranks 32 are arms 34, each of which is secured to a, rod 35 fastened to valve 26 and movable through the bridge-like guide 36. The extremity of each rod 35 is extended downwardly at 35 and moves in slot 37 formed in head 6, Figs. 3 and 4, thereby positively directing the movement of the valve. The valve vactuating mechanism operates as in my former patent to which reference may be made for detailed description.

When assembling the meter, the supplemental chambers are mounted on head 46, the faced neck portions 10 being secured thereto as will be understood, with the swinging guides 19 confined in the hook arms 20. The .valves and the valve actuating mechanisms are mounted on head 6 and placed in proper adjustment before the head ispositioned on casing 2. Pivoted latch 38 carried by bridge 36 permits screw stem 31 to rotate in one direction, but prevents the meter Afrom running backward,

this attachment being the same as in the patented structure excepting -for a slight .difference in its location.
